Derick gave a nice overview about what OSM is and showed some very interesting activities of the OSM community. He also mentioned some very convincing points why one should use OSM instead of Google Maps.

Elizabeth is normally a very engaging speaker. This talk was lackluster though, sadly. The talk was originally intended to be one hour long so to fit into the 15 minute slot, she just spoke very fast. That sadly didn't work so well :(

A very good introduction to non-blocking I/O and event loops in PHP, as well as a good overview about reactPHP. One demo didn't work quite as expected, but that's always a risk with live demos under unknown network conditions. Bonus points for the Half-Life / Portal reference, extra bonus points for Pony.

A very thought-inspiring keynote. Anthony highlighted how awesome we - the PHP community - can be when we unite and attack a problem together, and how dangerous it is for us to divide the community into silos. He called us all out to welcome everyone from the community, no matter their framework or CMS of choice, and to include and educate them instead of looking down upon them.
His reminder that we are all on the same team resonated with me and gave me a lot to think about.

A good introduction on how to parallelize phpunit's execution for fun and profit. I feel it could have been a bit more clear about the fact that the last example only times *startup* not the whole execution of the unit tests. There is definitely merit in the technique Mike presents though, and the presentation itself was great.
